Adobe Captivate 6 is yet another broken application from your favourite company, at least when it comes to enterprise deployment.
Here is the way it needs to be done.
1. Grab the latest version of the Adobe Application Manager Enterprise Edition from the Adobe website (ie at least V3)
2. Create the "main" Captivate 6 install by pointing AAMEE at the Captivate 6 folder/Win32 or Win64 on the installation media. This creates an MSI installer in the location you nominate, along with some folders of necessary files.
3. Create the "Add Ons" install by pointing the AAMEE at the Add-ons/eLearning Assets folder tree on the installation media.
Note that if you turn off the Adobe Update Manager in the configuration options, as is normal for locked down environments, you cannot run the VoicesInstaller.exe (another add-on) manually, as it is an "upgrade" in the Adobe world and you have just disabled them. However, since the VoicesInstaller.exe appears to be incapable of silent installation, and the assets1.zip file in the Voices subfolder is reported by AAMEE's upgrades generator function as an invalid ZIP file, there appears to be no way to deploy the voices using the source media.
So to deploy the voices, you need to perform a manual install of ALL the Captivate 6 components onto a test machine, and then, in the case of 32 bit installs, you need to harvest the C:\Program Files\Adobe\Adobe Captivate 6 (32 Bit)\VT folder which contains all the Voices, make this into an MSI and deploy it as the third package in the Captivate 'set'.
Incidentally, the Adobe Upgrade Manager is controlled in this manner:
Go to this location:
WinXp: C:\Program Files\Common Files\Adobe\AAMUpdaterInventory\1.0
There will be a AdobeUpdaterAdminPrefs.dat. Open this .dat file in notepad and then change the value from 1 to 0. Save.
